Hain was an associate of Morn's, involved in the LissepianMother's Day Heist along with three others. Upon hearing of Morn's death in 2374, he posed as a member of Lurian Security. He informed Quark that Morn was the ex-crown prince of the Royal Family of Luria, and that his riches were their property. This was a lie created to double-cross the other thieves. When all the conspirators met up in a cargo hold that supposedly contained the latinum stolen in the heist, Hain and the other thieves began arguing and shooting at each other. It all turned out to be a set-up devised by Morn to allow Odo to arrest the thieves. (DS9: "Who Mourns for Morn?")
